CPU Problems with Motu Symphonic and PT LE 7.4.2 & MacBook Pro

[elvi123]

Hi,

I am having trouble using MOTU Symphonic Instrument with Pro Tools LE 7.4.2
Even using only one instrument and one channel, the message, you are running out of CPU power pops up most annoyingly every time I press playback.

I recently bought a Mac Book Pro because I was sick of getting these messages with my Mac Powerbook but even then I was able to use a MOTU Symphonic instrument with a lot more plug ins, so I am baffled as to why my super new set up can't handle this instrument.

Even with default settings such as buffer 512 samples and RTA- 2 procesors CPU usage limit at 85 %, I should be having no problems with an instrument like MOTU. I'm baffled! AND FRUSTRATED!!!

Please anyone out there who understands how to fix this problem, I am most grateful for any help or advice.

Thanks, Elvi
